killer ruhal?

i think it is ruhal, cause if you see tomorrows preview, you can totally tell its a guy hitting sumit, you can tell by the force and body lang.
I think ruhal killed the blackmailer cause he was threating his daughter, maybe in a fit of anger, he just hit him and then guy ended up dying, i don't think ruhla actually planned on killing him, then i think he killed antra cause she found out somehow, and of course the doctor cause he too knew. He tried to frame his wife neeti, kind alike 2 birds with 1 stone. or maybe neeti killed antra and tried to frame siya dhruv?
so it is either ruhal alone or with neeti

So after tomorrow when this is all said and done, the next track by the looks of it is going to be sharman-siya-dhruv. Siya and shraman have gotten close due to this murder crap, and Siya is in the process of falling for shraman, and they also at the same time show Dhruv being jealous seeing the closeness between sharman and siya. I think siya and shraman are going to fall for each other, and dhruv is either alone or with neeti are going to try to force them apart. Since if ruhal is the murderer than neeti isn't married anymore sort of speak, and dhruv too is single since his wife is dead, so they both can technically if successfully tear apart siya and sharman, then they (as in dhruv and neeti) can be with siya and sharman.

So their plan is going to separate siya and shraman so they can be with them. Though i do think dhruv is going be -ve for all little while and with time will become good again.
